Check out the trousers on the guy at the switch.
I had a pair of knickers made out of the same material 80 years ago.
Never forget them for some reason.

In 1941 the Allison V-1710 had 1250 HP @ 3200 RPM...

Is this a V-12 or V-What?That engine must've have had some power! The size of that dyno-meter or hydra-matic! Any power specs?

V-12. So why at 4 valves per cylinder, are there only 11 exhaust tubes visible on port bank?

And knickers of the same fabric? Thankfully what passed for snazzy then, hasn't continued. Or coordinating plaids of hat and tie, lol.

I was wondering that also. I am thinking the 12th tube is blocked from view by that guys hand

On a bigger monitor [not my laptop] a bolt head and strap, alike with others holding tray beneath exhaust tubes IS visible. Shadow from cuff hides tube opening. Have to pursue picture link, and then + to get full size.

It sure is, a thing of beauty; evolved from pencil sketches, slide rules, and engineering intuition. Can't suppress my refrain; another reason a lot of us still speak English.
